Answer:

1. Ox-intercept is -4; y-intercept is 8.

2. Ox-intercept is 16; v-intercept is 20.

Step-by-step explanation:

1. -10x + 5y = 40

Recall the equation of line in slope - intercept form :

y = mx + c , where m is the slope and c is the y - intercept

Writing the given equation in this form,we have:

-10x + 5y = 40

5y = 10x + 40

y = 10/5 x + 40/5

y = 2x + 8

comparing with y = mx +c , then y - intercept is 8 , the x - intercept is the point at which y = 0 , substituting y = 0 into the equation , we have

0 = 2x + 8

2x = -8

x = -8/2

x = -4

2. Following the same procedure:

y = -5x/4 + 20

y - intercept = 20

x - intercept = 16

Answer:

11/15

Step-by-step explanation:

To answer this, add (combine) 1/3 and 2/5.

First we must rewrite these fractions with the same denominator, the LCD.

The LCD here is obtained by multiplying the denominators 3 and 5 together, obtaining 15.

Thus, 1/3 + 2/5 becomes 5/15 + 6/15, which, in turn, is 11/15.

The fraction of the total inventory that is children’s or women’s clothing

is 11/15.

Answer:

m = - 1

Step-by-step explanation:

Given

Multiply both sides by 2 to clear the fraction

15m + 3 = - 12 ( subtract 3 from both sides )

15m = - 15 ( divide both sides by 15 )

m = - 1

[tex]\text{Solve:}\\\\\frac{15m+3}{2}=-6\\\\\text{Multiply both sides by 2}\\\\15m+3=-12\\\\\text{Subtract 3 from both sides}\\\\15m=-15\\\\\text{Divide both sides by 15}\\\\\boxed{m=-1}[/tex]

Final answer:

The price of the jacket is $24.54, calculated by first finding the price of the shoes from the total cost and the price difference between the jacket and shoes, and then subtracting the difference from the price of the shoes.

Explanation:

The question at hand involves finding the price of a jacket given the total cost of the jacket and a pair of shoes and the relationship between their prices. Let's denote the price of the jacket as J and the price of the shoes as S. According to the information provided, we have the following two equations:

J + S = $52.95 (The total cost of both items)

J = S - $3.87 (The jacket costs $3.87 less than the shoes)

We can substitute the second equation into the first to find the price of the shoes:

(S - $3.87) + S = $52.95

2S - $3.87 = $52.95

2S = $52.95 + $3.87

2S = $56.82

S = $56.82 / 2

S = $28.41

Now we can find the price of the jacket by substituting the price of the shoes back into the second equation:

J = $28.41 - $3.87

J = $24.54

Therefore, the price of the jacket is $24.54.

With 2.5 litres of water, it can be estimated that you can make 400 grams of pasta.

The question is asking how many grams of pasta could be made with 2.5 litres (or 2500 ml) of water. According to the initial ratio, 500 ml of water is used to make 80 grams of pasta.

To find out how many grams of pasta can be made with 2.5 liters of water, you first need to find the pasta-to-water ratio which is 80 grams pasta to 500 ml water, or 0.16 grams/ml. You then multiply this ratio by the total amount of water you have:

0.16 grams/ml * 2500 ml = 400 grams of pasta.

Answer:

The consecutive even numbers are -42, -44, -46

Step-by-step explanation:

As the numbers are consecutive even integers,

Let,

The first number is "x"

The second number is "x+2"

The third number is "x+4"

According to the equation,

x + (x+2) + (x+4) = -132

As the sum is -132. Now we break the parenthesis by using the addition rule.

or, x + x + 2 + x + 4 = -132

or, 3x + 6 = -132

or, 3x = -132 - 6 (side change)

or, 3x = -138

or, x = -138/3 (interchange)

or, x = -46

Therefore, the first number is -46

The second number is -46+2 = -44

And the third number is -46+4 = -42

The consecutive even numbers are -42, -44, -46

It will take 4 years for these trees to be the same height

Step-by-step explanation:

A gardener is planting two types of trees:

Type A is 6 feet tall and grows at a rate of 12 inches per year

Type B is 2 feet tall and grows at a rate of 24 inches per year

We need to find exactly how many years it will take for these trees to be the same height

Assume that it will take x years for these trees to be the same height

Type A:

∵ The initial height of the tree is 6 feet

∵ 1 foot = 12 inches

∴ 6 feet = 6 × 12 = 72 inches

∴ The initial height of the tree is 72 inches

∵ It grows at a rate of 12 inches per year

∵ The number of years is x

∴ The height of the tree in x years = 72 + 12 x

Type B:

∵ The initial height of the tree is 2 feet

∴ 2 feet = 2 × 12 = 24 inches

∴ The initial height of the tree is 24 inches

∵ It grows at a rate of 24 inches per year

∵ The number of years is x

∴ The height of the tree in x years = 24 + 24 x

Equate The heights of the two types

∴ 72 + 12 x = 24 + 24 x

- Subtract 2 from both sides

∴ 48 + 12 x = 24 x

- Subtract 12 x from both sides

∴ 48 = 12 x

- Divide both sides by 12

∴ x = 4

It will take 4 years for these trees to be the same height

Answer:

The answer is C.

Step-by-step explanation:

Just failed hah stream fancy

Answer:

Answer is a^8/b^10

Option C

Step-by-step explanation:

((a²b-³)/(a-²b²))² where b and a are not equal zero

To solve this equation we start solving the equation from inside the bracket. And for simplicity we solve the numerator and solve the denominator before dividing them with each other. Now let get started

((a²b-³)/(a-²b²))²

Recall from indices that

a ^ -b = 1/a^b

I.e b-³ = 1/b³... We will apply this here.

((a²b-³)/(a-²b²))²

=((a²* 1/b³)/(b²*1/a²))²

=((a²/b³)/(b²/a²))²

Also recall that

(a/b) / (c/d) = (a/b) * (d/c)

Therefore

=((a²/b³)/(b²/a²))²

=(a²/b³ * a²/b²)²

Recall that: a^b * a^c = a^(b+c)

= (a ^ (2+2) / b ^ (2+3))²

= (a^4/b^5)²

Recall that: (a^b)^c = a^(b+c)

Therefore:

=™(a^4/b^5)²

=(a^(4*2)/b^(5*2))

= a^8/b^10

The homing pigeon will minimize its flying time by flying straight across the river, then directly to its nest. The time to fly this route would be 142.5 seconds.

The homing pigeon's path that will minimize its flying time would-be one where it flies straight across the river and then flies directly to its nest. The total time can be calculated by adding the time it flies over water and the time it flies over land. Initially, calculating the flying time over water, if the river is 500 meters wide, the time will be the distance divided by speed which equals 500m/8m/s = 62.5s . Now the land distance is the total distance minus the width of the river, so it would be 1300m – 500m = 800m. The time to cross this distance will be 800m/10m/s = 80s. Hence, adding both times, total flying time will be 62.5s + 80s = 142.5s. Therefore, the shortest path is firstly, flying straight across the river, and then straight towards its nest.

Final answer:

To find the previous year's total revenue, divide the current year's revenue by 1.34 since the current revenue is 34% higher than the previous year. The calculation shows that the previous year's revenue was $25,000.

Explanation:

The question asks us to find the total revenue of a small business for the previous year, given that the current year's revenue is 34% higher. To do this, we let x represent the revenue from the previous year. Since this year's revenue is 34% more than last year's, we have the equation:

1.34x = 33,500

To find the value of x, we divide both sides of the equation by 1.34:

x = 33,500 / 1.34

x = 25,000

Therefore, the total revenue for the previous year was $25,000.

Answer:

The diameter of the pizza is 12 inches

Step-by-step explanation:

Given:

Circumference of a pizza = 38 inches

To Find:

The Diameter of the pizza =?

Solution:

Circumference:

The distance around the edge of a circle (or any curvy shape). It is a type of perimeter.

We know that the shape of the pizza is circle.

So the given circumference is circumference of a circle.

Now,

Circumference of the circle(pizza)=[tex]2\pi r[/tex]

where r is the radius of the circle

circumference of the pizza =38

Thus

[tex]2\pi r= 38[/tex]

[tex]\pi r=\frac{38}{2}[/tex]

[tex]\pi r=19[/tex]

[tex]r=\frac{19}{3.14}[/tex]

r=6.050 inches

Now,

Diameter = [tex]2\times r[/tex]

Diameter = [tex]2\times 6.05[/tex]

Diameter=12.1 inches

Rounding to the nearest tenth

Diameter=12 inches

Final answer:

To find the diameter of a pizza with a circumference of about 38 inches, we apply the formula C = πD, leading to a calculation of 38 / 3.14, which results in approximately 12.1 inches.

Explanation:

The question is about finding the diameter of a pizza given its circumference, which is approximately 38 inches. To calculate the diameter from the circumference, we use the formula C = πD, where C is the circumference and D is the diameter. Since π (Pi) is approximately 3.14, we rearrange the formula to find the diameter: D = C / π. Thus, substituting the given value of C = 38 inches, we get D = 38 / 3.14, which is approximately 12.1 inches.

Answer:

53%

Step-by-step explanation:

subtract 6.5 - 4.25 = 2.25

then divide 2.25/4.25 = .529

times answer by 100 = 53% rounded

Answer: 53% increase

=============================================

Work Shown:

A = old value = 4.25

B = new value = 6.50

C = percent change

C = 100*(B-A)/A

C = 100*(6.50 - 4.25)/4.25

C = 52.94%

C = 53%

------------

notes:

The positive C value indicates we have a percent increase. If C was negative, then we'd have a percent decrease.

The formula shown above for C is basically having us compute the difference in price (B-A) and then we divide that difference over the original price A. This computes the decimal form of the answer. The "100*" tacked out front will convert from decimal to percent form.

If you took 52.94% of the original price 4.25, then you would get 0.5294*4.25 = 2.24995 which rounds to 2.25; this is the amount the price increases so we add this to 4.25 and we get 4.25+2.25 = 6.50 which is the new share price.
